In order to weaken NTT, the company was divided into a holding company (NTT) and three telecom companies (NTT East , NTT West , and NTT Communications) in 1999. The NTT Law regulating NTT East and West requires them to serve only short-distance communications and obligates them to maintain fixed-line telephone service all over the country.
